OBJECTIVE. We provide an outline of aortic anatomy and disease patterns, describe methods of aortic measurement, and highlight measurement thresholds for surgical intervention. We also discuss findings that can assist in preoperative planning and in detecting underlying connective tissue disorders. CONCLUSION. A standardized approach to the measurement of the aorta is needed and features suggestive of an underlying connective tissue disorder should be recognized. Radiologists should be aware of the image limitations and clinical implications of reported measurements.
